reagují

Reagují is a Czech verb form meaning "they react" or "they respond." It is the third-person plural present tense of reagovat, used when the subject is plural and the action takes place in the present.

In present tense, the verb conjugates as follows: já reaguji; ty reaguješ; on reaguje; my reagujeme; vy reagujete; oni reagují. The form is commonly used with phrases such as reagovat na co (to respond to something). Examples: "Oni reagují klidně na kritiku." "Když se situace změní, reagují rychle."

Etymology and usage notes: reagovat is a borrowing from French réagir, meaning to react. The corresponding noun is reakce, meaning "reaction," and the present participle is reagující, meaning "reacting." The verb is used across domains, from everyday conversation to journalism and formal discourse, to describe how people or systems respond to stimuli, events, statements, or changes. Synonyms include odpovědět in contexts emphasizing giving an answer, though reagovat more broadly covers any response or reaction.
